An ice cream parlour has changed the name of one its products after a "polite" request from Marks & Spencer. Fabio's Gelato, based in Hitchin, Hertfordshire, only began making its Percy Pig ice cream last week. But the retailing giant sent the owner Fabio Vincenti a letter which said he could continue to use the sweets, but not the name of the product. "It is what it is, they've got to protect Percy Pig," he said. Marks & Spencer said the name of Percy Pig, which started life as a bag of sweets in 1992 but has since evolved to other ranges, could only be used on "official M&S products". The letter said: "Percy Pig is one of our 'hero' brands and we own trade marks to protect it. "We risk losing those trade marks (and more importantly to us, consumers will no longer be confident Percy Pig-branded products originate from M&S) if we do not take steps to stop others from using them without our permission." Mr Vincenti said the ice cream had already proved popular online and would, for now, be renamed "Fabio's Pig".
